摘要:
An electromagnetic active engine mount apparatus includes a sub-channel through which working fluid flows is formed in the central portion of an electromagnetic drive so as to be able to cool heat generated from the coil of a solenoid section of the electromagnetic drive by repetitive operation of a vibrating member. Thus, the electromagnetic active engine mount apparatus can inhibit the heat generated from the coil to thus prevent thermal damage to various components formed of rubber, and provide improvement of its durability, reduction of its size, and simplification of its structure.

Disclosed herein is a wireless power transmission/reception apparatus and method having a communication function.The wireless power transmission/reception apparatus includes a wireless power transmission device and wireless power transmission devices. The wireless power transmission device receives a returned wireless power signal, detects the number of power consumption devices, modulates pieces of ID data, each including ID of a corresponding power consumption device, transmits the modulated ID data, receives returned ID data, and determines suitableness of the power consumption devices. Each of the wireless power reception devices returns a remaining wireless power signal which is not received among wireless power signals from the wireless power transmission device, and temporarily stops a power consumption device when an ID of the received ID data is an ID of a power consumption device connected thereto, thus returning ID data which will be subsequently received to the wireless power transmission device.
